Description

Overview

Thermo King drive coupling bushing suits SB, SL and SLXi compressor drive applications and supports X426 and X430 compressor service. It sits in the drive coupling, so it helps control movement where the compressor drive transfers load. When a worn bushing starts to loosen up, the coupling can show extra play during clutch or compressor work.

Features

• Supports SB, SL and SLXi drive coupling service.
• Matches X426 and X430 compressor drive applications.
• Useful when coupling wear, looseness or movement shows up during inspection.
• Includes interchange numbers below for workshop matching before order.

Specifications and Materials

Thermo King drive coupling bushing is an aftermarket one-piece replacement bushing for compressor drive coupling service. It suits workshops that need a clean match against older part numbers and established compressor families before fitting.

Part number: TK-77-2856-AM.

Compatibility and Fitment

Match the unit family, compressor family and the existing coupling bushing before ordering, especially when older service history is involved. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 77-2856, 772856, 1E34723G01, 77-2145, 772145, 1B15304G01, 77-2748, 772748, 1E12388G01, 77-2810, 772810, 1E12388G02

Compliance and Safety

Isolate the unit before drive coupling work, because rotating components and stored drive energy can create risk during service. If the clutch or coupling area shows scoring, cracking or abnormal dust, replace damaged surrounding parts at the same time. Also check alignment, fasteners and adjacent drive parts before the unit goes back into service. That extra check matters because a fresh bushing will not fix wear caused by a loose or damaged coupling assembly.

Trailer Applications

Thermo King drive coupling bushing fits trailer refrigeration service where SB, SL and SLXi units run X426 or X430 compressor drives. Workshops usually replace it during clutch or coupling repairs, and it also makes sense when the drive assembly is already apart for compressor work. In fleet maintenance, this part often sits with other small drive components that are cheaper to change during one strip-down than after repeat labour later.
